Answer:
4^-8
Step-by-step explanation:
When multiplying two exponents with the same base, in this case, 4, you need to add the two powers (-6 + -2), to get -8.
The HCF for the three sets of algebraic expression is 32b.
<h3>HCF of algebraic expression</h3>
The HCF of an algebraic expression is the highest common factor present in between given two or more numbers or mathematical expression.
we shall derive the HCF of the algebraic expression by first expressing them as products of the their prime factors as follows;
32a × 5b × 4 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 5 × a × b
24a × 6b × 6 = 2 × 2 × 2 × 2 × 2 × 3 × 3 × a × b
48a × 4b × 5 = 2 × 2 × 2 × 2 × 2 × 2 × 5 × b
Then;
32a × 5b × 4 = (2^5) × b× 2 × 2 × 5 × a
24a × 6b × 6 = (2^5) × b × 3 × 3 × a
48a × 4b × 5 = (2^5) × b × 2 × 5
Hence, the HCF = (2^5) × b
HCF = 32 × b
HCF = 32b
Therefore, we can say that the HCF of the given algebraic expressions is 32b.

Hey there! :)
Answer:
D : [-4, ∞)
R: [-2, ∞)
Step-by-step explanation:
Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:
[ is used for closed points.
( is used for arrows or open circles.
Therefore:
This graph goes from x = -4 towards x ⇒∞. Therefore:
D : [-4, ∞)
The range of this function goes from x = -2 towards y⇒ ∞. Therefore:
R: [-2, ∞)

Answer:
She should find the squares between 4.2 and 4.3
Step-by-step explanation:
The square of 4.2 was too low and the square for 4.3 was too high so the answer is between the two.
